DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present device a soffit venting system shown in FIGS. 1 and 2 whichdepicts generally a soffit vent section 100 which has indefinite lengthalong the longitudinal direction 128. The soffit vent section 100 can becut to any particular length for example the length shown in FIG. 1which includes three vented sections 124.

Soffit vent section 100 includes a left wall 102 connected at a lowerend 112 to a right wall 104 defining an apex 113 and a V shaped section.Lower ends 112 of walls 102 and 104 make contact with bottom edge 114 ofbaffle 106. Baffle 106 preferably having a corrugated edge 108 which isa S pattern configuration as depicted. Baffle 106 also has a bottom edge114 and a baffle height BH 141. Preferably the baffle height BH is equalto the vent height H 145.

Soffit vent section 100 further includes transversely oriented crossbraces 116 spaced periodically along the longitudinal direction 128 inorder to hold baffle 106 in the correct central position. Vent section100 has a width W 143.

Soffit vent section 100 further includes a left flange 118 and a rightflange 120 which preferably includes apertures 122 periodically spacedalong the longitudinal direction of each of the left and right flange118 and 120 which are used to fasten the soffit vent section to asoffit. Flanges 120 and 118 may not have apertures in the instance thevent section is glued or other wised affixed to the soffit with forexample brackets.

Soffit vent section 100 further includes vented sections 124 whichincludes louvers 126.

Preferably louvers 126 are oriented perpendicular to or at a right angleto either the left wall 102 or the right wall 104 in order to maximizedeflection of the air into the interior 130 of soffit vent section 100.

Referring now to FIGS. 3 and 4 which show a soffit vent cover showngenerally as 200 which unlike soffit vent section 100 does not have anindefinite length along the longitudinal direction 228 but rather ismade to specific dimensions depending upon the venting requirements.

Soffit vent cover 200 includes a left wall 202, a right wall 204 and theend walls 205 which all come together at a wall end 207. This forms apyramid-like shaped structure shown and depicted as soffit vent cover200 in the case both ends are closed off. Soffit vent cover furtherincludes baffle 206 which has a corrugated upper edge 208 having a Spattern configuration and is preferably held in place centrally by atleast one cross brace 216.

Soffit vent cover 200 has an upper end 210 which defines upper flange219 around the entire periphery of soffit vent cover 200. Upper flange219 also preferably includes apertures 222 which are used to fasten thesoffit vent cover to the soffit.

Soffit vent cover 200 further includes vented sections 224 which includelouvers 226 which preferably are oriented at a right angle orperpendicular to the left wall 202 and right wall 204 of soffit ventcover 200. Left wall 202 and right wall 204 come together and are joinedat lower end 212 of soffit vent cover 200.

Referring now to FIGS. 5 and 6 which show schematically cross section inFIG. 5 in a perspective view in FIG. 6 a fascia 302 together with asoffit 305 which is mounted to a roof joist 312 and a wall joist 314.

Fascia 302 in this case is a straight fascia 304 which normally is madeup of a fascia board 306 having a fascia lip 308 which is normallydefined as the lip overhang 310 as shown in FIG. 5. The present soffitventing system is shown generally as 300 includes in combination afascia 302 having long lip overhang 310 together with a soffit ventsection 100 mounted in the soffit 305 of the building construction asshown in FIG. 5.

In this manner lip overhang 310 will tend to deflect and retain the airwithin the area between the wall joist and the fascia board therebydirecting and deflecting air into the soffit vent section 100 and upinto the roof cavity 330.

Referring now to FIG. 7 which is similar to FIGS. 5 and 6 however withthe further inclusion of showing airflow direction namely arrows 340 inFIG. 7.

The reader will note that fascia 304 includes a fascia portion F 351which is the portion beginning adjacent the roof line and covering theend of the roof joists 312 and extending to the bottom of the soffit.Fascia 304 also includes a lip portion L 353 which is the length of thefascia below the bottom of the soffit 305. Lip portion L 353, alsodenoted the lip overhang 310, deflects the air around the fascia andchannels the air between the wall joists 314 and the lip overhang 310and into the vented sections 124. The air is channelled through thelouvers 126 of soffit vent section 100 and up through the vent hole 316which is located in the soffit 305 and up through the roof cavity 330wherein the warm or hot air is exiting through roof vent 342 as inconventional roof venting systems.

Referring now to FIG. 8 which is in many aspects the same as soffitventing system 300 showing soffit venting system 400 which includes afascia 402 and a step fascia design 404 having a fascia lip 408 and alip overhang 410.

Soffit venting system shown generally as 400 is a step fascia design 404deployed together with a soffit vent section 100 and mounted on a fascia402 and a soffit 405 together with roof joist 312 and wall joist 314.

In practice the inventors have found that the step fascia design furtheraids in the deflection of air around the lip overhang 410 and then theair is channelled into soffit vent section 100 as shown in FIG. 7.
